Biospecimens

Part of speech: noun

Definitions

1. Samples of biological material collected for research or medical analysis, such as tissues, blood, or cells, used to study health, disease, or genetics

3. Biological samples taken from organisms to facilitate research, testing, or medical investigations, commonly encompassing various bodily fluids and tissues

Etymology: The word is a modern compound, and its two halves come from different centuries and languages. "Bio-" traces back through ancient Greek "bios", meaning life, to a Proto-Indo-European root for living. "Specimen" came into English from Latin "specimen", a sample or proof, built from "specere", to look at. Joining the two gives a term for material taken from a living source and examined under a lens, which is what the word is for. The combination is a product of recent scientific practice rather than classical usage. Ancient Greeks had "bios" and Romans had "specimen", but neither could have written "biospecimen"; the joining reflects how modern research has come to treat tissues and fluids as collectible, storable objects. The plural, "biospecimens", simply follows the usual English pattern of adding an "-s" to a count noun.

Synonyms: biological samples, tissue samples, biological specimens
